Method for producing a thin film resin matrix

Abstract

The present invention provides a method for producing a a high-performance black matrix taking the palce of a Cr film black matrix and a high-performance color display thin film, which is comprises steps of vaporizing one or more organic pigments or vaporizing and exciting a metal or an alloy together with said organic pigments, and forming a thin film or a mixed composite thin film onto a substrate by the plasma exciting deposition.
